MozPlugger is a generic Mozilla plug-in that allows the use of standard Linux programs as plug-ins for media types on the Internet. MozPlugger will help the Mozilla / Gecko based browsers to handle a variety of file formats like pdf, office formats (xls, xlsx, ppt, pptx, doc, docx), LibreOffice file formats etc. Without installing mozplugger we find that very few file types are present in "Helper Applications" window in both SeaMonkey and Firefox.

SeaMonkey with few content types in Helper Applications

Firefox also shows only a few content types in Application preferences

When i try to open a sample xls file hosted online SeaMonkey tries to download and open it outside the browser.

The Nautilus-Image-Converter is an extension that allows you to resize / rotate images from Nautilus. This extension is very useful when uploading images to websites (size limitations), creating thumbnails etc.

Step3:- Using zypper we can install the relevant extension using command "sudo -u root zypper in nautilus-image-converter".

Step4:- Use the context menu (or) right click menu to "rotate" and resize images. The extension automatically appends a ".resized" and ".rotated" string to the names of newly created files, lest the original file gets overwritten.

If you are not comfortable with running systemctl / systemd commands from console / terminal then you can install "systemd-ui" which acts like a Graphical front-end for systemd system and acts like a service manager.
